i iZ n00b !!

Hey Guys,

I am new to the DSLR world and all the technical terms are new for me...i am a quick learner though

Foremost, I bought a Nikon D3100 with a AF-S 18-55mm, 55-200 mm lenses but dont know how to use to their max. efficiency...thats how a n00b thinks !!

I would need some help regarding some very basic issues :

1. My first worry is the cleaning, protection and maintenance of the lenses as they get fingerprints, dust, moisture-like formation thanks to the monsoon here in Mumbai ...so any protection or proper cleaning methods will be helpful.(Currently I seldom wipe the lens with a soft tissue )

2. To efficiently use the DSLR like. preserving the battery when camera not in use, cleaning the [Image Sensor, mirror, low pass filter]* and the body of the DSLR.

* What are their functions

3. Despite several times reading the manual for the P S A M modes i understand them but fail to apply them when needed..so switch back to Auto as i dont want to ruin the moment; but would love to use the Manual modes and know the terms like Shutter speed, Aperture, Exposure and their co-relation to one another in simple terms.

wooh....Kindly spoon feed to get my basics straight practically.

Thanx in Anticipation.


Regards,

assleo

Welcome to Pixalo Assleo

I can imagine that in your environment, keeping your kit clean can be a problem. First see what (if any) information is given in the camera and lens manuals. The camera and lens bodies are usually roughened and/or rubberised so you can grip them better, so cleaning can be difficult. If you have any sand/grit.dust on the bodies - perhaps from the wind depositing it - you need to remove it carefully to prevent any scratching. A blower or brush (or both) will probably do this. The lens glass is much more delicate and it might be wise to use UV or Skylight filters to offer some protection to the lens glass. Again, a blower and/or a very soft brush is always a good starting point and you can also use lens cleaning tissues or a microfibre cloth or a jeweler's polishing Selvyt if there is no grit present. You can also get lens cleaning fluid - use sparingly - and tissues impregnated with a cleaning fluid. Protection against moisture is more difficult if it is simply due to humidity. But the moisture in the air will only be a problem if you move into a cooler temperature that can cause condensation. Perhaps not so much of an issue for you.

When not in use keep the battery in the camera or the internal rechargeable battery that remembers all of your settings will run flat. It will last for a reasonable time to allow the main battery to be charged. Don't know about the D3100, but my old Nikon D70s had a fantastic battery life giving on test over 2500 shots. I had a week on holiday and did it on one charge! I've not touched it for about a year and the battery still has a decent charge. Very impressive. If your battery does not last as long it might be worth getting another one so you can have a reserve.

If you take care when you change your lens and be aware of the potential for getting dirt inside the camera it will help a lot. You will not have to clean the sensor regularly and there are lots of kits to enable you to do this. Everyone will advocate the one that they use, so you can only really do the research to see what system will suit you best. I use a Sensor Klear pen on the rare occasions that I need to remove dust deposits from my sensor.

LENSPEN is The superior Camera lens cleaning system for all fine optics, rifle scopes, camcorder and camera viewer screens, binoculars

Sensors have a limited capacity for processing light so the low pass filter filters out the high frequency waveband light. There are some technical reasons why the high waveband light is filtered, and it is also the reason why digital images have to be sharpened either in camera if you shoot in jpeg, or in processing if you shoot in RAW format. The low pass filter protects the actual sensor physically too.

The best way to expand your knowledge with the camera modes is not to attempt to do everything at once. Most people will use aperture priority mode for general purpose use so study apertures and how they affect focus and shutter speed first. All of the settings will have an effect on other elements of photography, so gradually you will build up the combinations of aperture, shutter speed ISO and all of the other settings, and where to use the most appropriate mode.
